During the blank Roman generals warded over succession. These conflicts drew soukderw away from the frontier

During the late Roman Republic, several generals vied for power and influence, which led to a series of civil wars known as the Roman Succession Crisis. These conflicts diverted soldiers away from the Roman frontier, as they were needed in the internal power struggle.

One of the most significant succession crises occurred after the death of Julius Caesar in 44 BCE. This led to a power struggle between Caesar's adopted heir, Octavian (later known as Augustus), and other Roman generals, including Mark Antony and Lepidus. This conflict, known as the Second Triumvirate, lasted until the final defeat of Mark Antony by Octavian in the Battle of Actium in 31 BCE.

During this time, the Roman legions were often mobilized to support one general or another, resulting in a drain of military resources from the frontiers. The Roman army, particularly in regions such as Gaul (modern-day France) and Germania (modern-day Germany), faced challenges as troops were diverted to fight in the succession wars and maintain control of the Roman state.

The instability caused by these conflicts also created opportunities for external enemies, including barbarian tribes and rival powers, to exploit Rome's distracted state. This further weakened the Roman frontier defenses and contributed to the decline of the Roman Empire.

Ultimately, with the establishment of Augustus as the first Roman Emperor in 27 BCE, the succession crisis was resolved, and stability was restored to the Roman state. However, the diversion of soldiers from the frontier during this period had long-lasting consequences for the Roman Empire's ability to defend its borders effectively.

During the Roman Empire, several periods of succession conflicts occurred, which diverted military resources away from the frontier. One notable period of conflict was the Crisis of the Third Century, which lasted from 235 to 284 AD.

1. The Crisis of the Third Century began with the assassination of Emperor Alexander Severus in 235 AD. This event triggered a series of power struggles, civil wars, and usurpations that plagued the Roman Empire for almost fifty years.

2. Numerous generals and military commanders emerged during this period, each claiming the title of Emperor and vying for control over the Roman Empire. These generals, known as "usurpers," often had the support of the armies under their command.

3. As these succession conflicts erupted, the Roman legions stationed on the frontiers were frequently drawn into the power struggles. The armies, originally tasked with defending the empire's borders from external threats, were now being utilized by rival claimants for their personal gain.

4. This diversion of military resources from the frontier compromised the Roman Empire's ability to defend against external enemies, such as barbarian invasions. The weakened defensive capabilities allowed various Germanic tribes, including the Goths and the Vandals, to raid and penetrate Roman territories.

5. The weakened state of the Roman Empire during the Crisis of the Third Century led to a severe decline in centralized governance and economic instability. The continuous conflicts, coupled with economic hardships, further eroded the empire's ability to effectively protect its borders.

6. However, it is important to note that succession conflicts and the diversion of soldiers away from the frontier were not limited to the Crisis of the Third Century. Similar situations occurred at various points throughout Roman history, such as during the Year of the Four Emperors in 69 AD and during the reign of Constantine the Great in the early 4th century.

Overall, the conflicts and power struggles among Roman generals during periods of succession had negative consequences for the defense of the Roman Empire's frontiers, allowing external threats to exploit weaknesses and penetrate Roman territories.
